I am updating to Xcode 12.4 from Xcode 12.3 on MBP 16" 2020 - Big Sur 11.2.1. I noticed that App Store took around hour to only update xcode. Firing up system monitor, I found installd wrote 15 GB and read 59.7 GB. I think this is not normal at all. the huge amount of read GB is deceitful for me. Any more insights on that ?
